Need Help Recovering Encrypted Files (WinRAR or Windows Encryption)

Hello,

I need help recovering access to a folder or archive that I encrypted with a password using WinRAR (or possibly Windows encryption). The strange thing is that I was initially able to access the files with the password, but after a short while (about 1–2 hours), the password stopped working and now I can't access my files at all.

I’m looking for a Windows expert or data recovery professional who can:

- Help me recover the original files before encryption or password change
- Possibly restore a previous version of the folder using Windows tools (like File History or System Restore)
- Provide guidance or tools (free or affordable) to access the files again

I did NOT forget the password. It simply stopped working for unknown reasons.

This is for personal use only, and I can prove ownership of the files if needed. Please let me know what info or screenshots you need.

Thanks in advance!
